Coleus plant named ‘SAKCOL019’

ABSTRACT

A coleus plant particularly distinguished by large leaves and yellow-green leaves with green margins, is disclosed.

Genus and species: Solenostemon sp.

Variety denomination: ‘SAKCOL019’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of coleus,botanically known as Solenostemon sp., and hereinafter referred to bythe variety name ‘SAKCOL019’.

‘SAKCOL019’ originated from a cross-pollination conducted in October2012 in Kakegawa, Japan among multiple plants of six unpatentedproprietary coleus lines designated ‘0-8C-3A-1B-5B-11D-3’, ‘12TH-2’,‘12C-3’, ‘12M-4’, ‘12H-5’ and ‘12TL-1’. The cross-pollination wasconducted in a cage using bees. 2,600 seeds were harvested from the‘12C-3’ plants. The seeds harvested from the ‘12C-3’ plants are composedof hybrid seeds and self-pollinated seeds.

The seeds obtained from the ‘12C-3’ plants were sown and a single plantselection designated ‘L2013-CO040’ was selected for its multi-coloredleaf pattern displaying a yellow-green leaf and rose colored veins,creeping plant habit and small leaves. The breeder confirmed that‘L2013-CO040’ was fixed and stable. ‘L2013-CO040’ was subsequently named‘SAKCOL019’.

The new plant was first asexually propagated in 2013 in Japan and hasbeen asexually reproduced by vegetative cuttings for almost three yearsin Japan. The present invention has been found to retain its distinctivecharacteristics through successive asexual propagations by vegetativecuttings.

‘SAKCOL019’ has not been made publicly available or sold more than oneyear prior to the filing date of this application.

SUMMARY OF THE NEW PLANT

The following are the most outstanding and distinguishingcharacteristics of the new variety when grown under normal horticulturalpractices in Salinas, Calif.

-   -   1. Large leaves; and    -   2. Yellow-green leaves with green margins.

DESCRIPTION OF THE PHOTOGRAPHS

This new coleus plant is illustrated by the accompanying photographswhich show the overall plant habit, and foliage of a plant aged 7 monthsold. The colors are as true as can be reasonably obtained byconventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘SAKCOL019’. The data which defines thesecharacteristics were collected from plants grown 7 months fromtransplant into 4-inch pots from rooted cuttings in Salinas, Calif.,under greenhouse conditions. Color references are to The RoyalHorticultural Society Colour Chart, 4^(th) edition. Anatomic labels arefrom The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickeyand C. King, Cambridge University Press.

The vegetative    cuttings were propagated for five to six weeks. The base of the    cuttings were dipped for 1 to 2 seconds in a 1:9 solution of DIP 'N    GROW (1 solution: 9 water) root inducing solution immediately prior    to sticking into the cell trays. Cuttings were stuck into plastic    cell trays having 98 cells, and containing a moistened peat    moss-based growing medium. The cuttings were misted with water from    overhead for 10 seconds every 30 minutes until sufficient roots were    formed. Rooted cuttings were transplanted and grown in 20 cm    diameter plastic pots in a glass greenhouse located in Salinas,    Calif. Pots contained a peat moss-based growing medium. Soluble    fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium    was applied once a day or every other day by overhead irrigation.    Pots were top-dressed with a dry, slow release fertilizer containing    20% nitrogen, 10% phosphorus and 18% potassium.
